The start: 0 to 100 km/h

Off the line, the Roma hits 100 km/h in 3.43 s versus 4.56 s for the 718 Cayman. At this point, the Roma leads by 1.13 s and sits roughly 9 m ahead.

From 100 km/h to 400 metres

At 200 metres, the Roma is doing 182 km/h against 149 km/h for the 718 Cayman. The gap is 1.17 s. The gap remains stable from the start.

At 400 metres standing start, the Roma crosses the line in 10.68 s versus 12.65 s. The 1.97 s gap represents roughly 97 m of track - a gap visible to the naked eye.

Beyond 400 metres: top speed comes into play

Past 400 metres, the Roma continues to build its lead. At 600 metres, it runs at 256 km/h versus 206 km/h. At 1,000 metres, the Roma finishes in 18.88 s versus 22.89 s, with a 4.01 s lead.

What the numbers don’t tell you

Electronically capped at 274 km/h, the 718 Cayman never reaches its natural aerodynamic ceiling in this duel. That’s not a physical limit of the motor - it’s a deliberate manufacturer decision, typically tied to standard-fit tyre ratings or model-range positioning.

With two combustion powertrains, the difference comes down to power-to-weight ratio (2.37 kg/hp vs 4.45 kg/hp) and transmission (Automatic vs Automatic).

In European road use (130 km/h max), both vehicles reach the legal speed limit in under 6.70 seconds. The 1.13 s difference in 0 to 100 km/h is mostly felt in motorway merging and overtaking.
